These guys built a $273 million startup from discarded computers and an almost secret source of seed money

ThousandEyes is one of those hot, successful startups you
probably never heard of with an unusual and not-very
Silicon-Valley-like history.

Founded in 2010 by CEO Mohit Lad and CTO Ricardo
Oliveira from their grad school work at UCLA, ThousandEyes helps
ensure that when bits of the internet go down, companies can
avoid being taken down too — even if the problem is on the
internet and out of their control.

"We worked together at UCLA doing our PhDs understanding how
things break the internet, and how that impacts the rest of the
internet," Lad told Business Insider.

ThousandEye's customers include Twitter, Equinix,
ServiceNow, eBay, DocuSign, six of the top US banks, and many of
the top software-as-a-service cloud companies.

The company currently employs over 130 employees and is
doubling revenue annually, with good enough cash flow that it
never needed to raise venture funding just to survive, Lad told
us.

And that means that VCs have been tripping over themselves to
invest. ThousandEyes has taken $60.5 million of investment
over three rounds, at a valuation of $273 million after the last
round in February, according to
PitchBook.

And it all began with a bunch of computer servers that the
founders scrounged out of big corporate electronics recycling
bins and from a second-hand computer store in Sunnyvale known as Weird Stuff.

Big idea, no money

When they came up with their idea to build a brand new kind of
network monitoring software, one that could watch the whole
internet and not just one company's internal network, they
quickly realized several things:

In order to see the whole internet and measure it very
precisely, they couldn't be using the very same internet cloud
services they were monitoring, like Amazon Web Services. They had
to have control over their own computers and equipment so they
had to have their own data center.

And then they realized ...

Building a data center is very expensive.

They didn't have much money.

They didn't want to spend their time pitching VCs.

"We could go to Sand Hill road and spend months trying to raise
money, or we could try to build a product and really get it off
the ground and get customers. We chose the latter route and in
hindsight it was one of the best decisions we made," Lad said.

"If you have an idea which is high risk, that has a lot of
R&D, the NSF tends to like it," Lad told us.

The upside of an NSF grant was that they didn't have to sell off
a chunk of equity in their company to an angel investor. The
downside? The money was doled out in smallish chunks every six
months.

"We started in 2010 and we got about $1 million and change from
them, which is a good grant. But it took two years for the whole
thing to come," he said.

The grant gave them just enough money to quit their jobs and live
frugally while they built their product.

But the six-month deadlines were also a blessing in disguise.
They had to show progress to get the next chunk of cash and they
had to stay laser focused on building something good and
marketable from the get-go.

"We didn’t have this large seed investment that we could take to
the bank and start to hire people and whiteboard a product
idea. We had very little in the bank, so the entire focus of
the founders and our VP of engineering at that point was around
how to do you build something that the market will just adopt
right away," he said.

Driving around, picking up discarded servers

With cash tight, they couldn't spend much on the computer
servers they needed, either. Most other startups get around that
by use a cloud service like Amazon Web Services, which lets them
cheaply pay only for the amount of computing time they use.

andEyes couldn't do that, so they came up with a clever idea to
build their data center with computers that were older
cast-offs.

"Sometimes companies would recycle servers. They would shut down
a lab and put the servers in the electronic recycle area and they
were up for grabs. We would just go by and pick up a few servers
and load them in the trunk," he remembers, adding that they were
literally driving around "picking up servers."

They also bought used servers from a place in Sunnyvale called
Weird Stuff. "It used to be a common stop for us," Lad said.

They built the company's first data center in their garage with
all of those old, discarded servers.

Frustrated tweets = customers

With the product built and hosted on their home-grown data
center, the next step was to find customers. Normally, that's
when a well-connected VC helps, giving introductions to
enterprises willing to take a startup under their wing.

ThousandEyes didn't have any VCs. But it had something better. It
was watching the internet and knew which companies were
struggling to stay online ... and why.

In the early days, they would scan Twitter "to see who was having
an issue, who was having an outage," Lad said.

"We would hit them up cold, and send them information on what
went wrong, outside of their environment or with their ISPs, tell
them why users in a certain region weren’t reaching them," he
said.

Impressed and in need of help, these companies began signing up
as ThousandEyes customers.

By 2013, when the startup formally came out of stealth, "We
had Fortune 20 companies using ThousandEyes with no prior
relationship with these guys."

"It’s more difficult to get customers on your own, instead of VC
referrals, but the good thing is, when you get customers on your
own, they will stay with you forever because you are solving a
key problem for them," he said.

Sorry Mr. VC, I don't have time to pitch you

These customers told others about ThousandEyes and business grew
quickly through word of mouth. In the summer of 2013,
Lad was speaking at an industry conference where Aaref
Hilaly, a VC with Sequoia, heard him and expressed interest his
company.

"We weren’t fund raising," Lad said but he agreed to a meeting at
the VC's offices. "We told them, 'Look, we’re focusing on
customers so we can’t really build [pitch deck] slides at this
point.'"

Instead, the founders showed the VCs a demo of the product. And
they walked with a $5.5 million Series A.

Lad has gone on to have two other rounds for a total of $60.5
million, all of the rounds came from "inbound" interest from VCs,
Lad said. ThousandEyes backers include Sutter Hill, Tenaya
Capital, GV (formerly Google Ventures), and Salesforce.

"My philosophy on funding is that funding is to scale, it’s not
to survive. So at any point when we’ve gone to the [VC] market,
it’s because we’ve done some validation for the next phase of the
company and we think we can take it to the next level," he said.

"What also made the fundraising easy is that the fundamentals of
the business are very strong for this stage of the company. This
is where that painful early bootstrapped growth actually helps,
because our unit economics are very strong, our cash flow is
really good," Lad said.

In February, ThousandEyes took on $35 million and by August, it
still hadn't touched a dime of it, Lad told us. They took the
money because VCs were pretty much clamoring to invest and
it was easier to just take it then, than spend time looking for
investors later.

"When we did our last round, we didn’t need the money," he said.
"We decided we should get it out of the way to focus on building
the company."

Since then, ThousandEyes has launched new products, opened an
office in Austin, in addition to the San Francisco headquarters
and an office in London.
